Lette/11s Patent No. 86,925, dated .February 16, 1869.

The Schedule referredI to in these Letters Patent and making part of the same.

To all whom it may conce/rn:

Be it known that I, GEORGE H. JOHNSON, of the city ofBuii'alo, county of Erie, and State of New York, have invented an Improved Construction for Grain- Spouts; and I do hereby declare that the ibllowing is a full, clear, and exact description thereof, reference being had to the accompal'iying drawings, making :l part of this specification.

In grain-elevators and store-houses, the receiving, distributing, and discharging-spouts constitute important features, not only in respect to the functions which they perform, but also as a very material item in the cost of Such struclures.

In fire-proof Structures, they require to be made of metal, and their cost is, therefore, greatly enhanced.

Grain, moving through Spouts at a high velocity, creates excessive friction upon the bottom and sides thereof, which, in time, abi-arles and cuts through the saine, while the top, which is not subject to such friction, .will last for a much longer time.

My invention has i'or its object the construction of metallic grain-spouts, which shall possess the greatest durability, with the least weight of material, and, consequently, least cost of construction; and

It consist-s in the combination of a metallictrough, of suitable thickness, for the bottom and sides of the spout, in view oi' the friction and wear to which they are subjected, with a light sheet-metal covering, to prevent the escape of grain and dust from the trough, whereby the above-mentioned objects are fully accomplished. ',lhe accompanying drawing shows, in perspective, a section oi' my improved grain-spout.

The trough, which is preferably made Otl cast-iron, is shown at A, land the sheet-metal covering at B.

The trough, as represented, is rectangular in crosssection, but it may be made oval or semicircular.

The sheet-metal covering may also be either rectangular, oval, or semicircular in cross-section, though rep resented in the drawing as oval.

The covering, in either case, laps inside of the trough, as shown at c, and is secured thereto by rivets, cl. The spout may be made in sections of any desired length, and connected together, as shown at E, after the manner of a stove-pipe joint, except that the trough-sections are rebated at one end to receive the end of the contiguous section, so that the bottom of a spout, composed of several sections, may be flush and smooth.

Having thus described my invention, What I claim, and desire to secure by Letters Patent ismetallic grain-spout, composed ofthe parts A and B, substantially as herein described.
